Question

【题目】The students have been working hard on their lessons and their efforts __________ with success in the end.

A. rewarded

B. were rewarded

C. will reward

D. will be rewarded

Answer 1

【答案】 D

【解析】考查时态和语态。句意：学生们一直在刻苦学习功课，他们的努力（将来）一定会得到回报。根据句意可知，回报是将来要发生的事情，应该用将来时；efforts和reward是被动关系，应该使用被动语态，故选D。
